aye, some of the engineers have no clue at all like.
It's a pain for the call centre's to deal with as well when they make a mess or don't turn up, cause it can't be sorted straight away.
If your dish has to go higher, it needs to be put to a "special heights" team for insurance purposes, which takes even longer. I hate those types of call, lol.
Good that you got it sorted EVENTUALLY though.
